After his last bout, it became especially apparent that dos Santos is slowing down significantly. It’s one thing to make in-fight errors or face elite competition, but it’s clear from his last victory against a favorable style match up that dos Santos doesn’t quite have the speed or reaction time that once carried him through fights. All the same, “JDS” is a skillful veteran and more than a match for much of the division. Tuivasa, meanwhile, is a Heavyweight under 30 years of age who is not a complete slob, automatically making him a quality prospect. In addition, there’s some sneaky set ups and explosiveness behind his game, possibly enough to catch the veteran off-guard and end things early.
